Part 5/13:
A core aspect of Hancock’s thesis revolves around a series of catastrophic events approximately 12,800 years ago during the Younger Dryas period. Evidence from geological surveys, impact proxies like nano diamonds, melted quartz, and iridium layers strongly suggest a massive influx of extraterrestrial objects—comet fragments hitting Earth and inciting global crises.
He describes the impact hypothesis, where a disintegrating comet’s debris stream struck Earth, causing widespread flooding, climate upheaval, and the destruction of advanced civilizations. The signs of airbursts (meteors exploding in the atmosphere) and massive flooding—evidenced by the scablands of North America—are correlated with impact dates around 12,800 and 11,600 years ago.
